Update to Ethereum trace methods #2473
Description
Per IDOC-528 for Ethereum mainnet and Sepolia:
Trace handling: Responses are now handled generically, like other services, allowing dynamic support for newly introduced fields without requiring code changes.
Off-chain databases removed: As a result, trace_filter is now limited to 100 blocks per query. The previous behaviour was only bound by the number of traces returned.
New field: creationMethod is now returned in traces.
Reward traces: Post-merge blocks previously returned reward traces as 0 and are now removed. Indexers may see discrepancies for those blocks.
